BENCH-CLAMP.

Specification of Letters Patent.

Patented Nov. '7', 1916.

Application filed June 24, 1914. Serial No. 847,063. 1

To all whom it may concern Be it known that 1, JAMES M. BRILES, acitizen of the United States, residing at Victoria, in the county ofVictoria and State of Texas, have invented certain new and usefulImprovements in Bench-Clamps, of which the following is a specification.

The object of this invention is to provide a bench clamp having one ormore grips for engaging the work at different elevations so that if itis desired to plane or otherwise finish or dress a flat side of stock,one of the grips may be used to engage the stock adjacent the surface ofthe bench, and if it is desired to plane or dress ,a side edge, thenboth of the grips may be adjusted to engage the stock at differentelevations and hold .it in an upright position with its edge in anexposed relation for engagement by the dressing tool.

It is a special object of my invention to simplify bench clamps andprovide means whereby the upper grip may be moved out of an operativeposition and out of a position above the surface of the bench when notin use. 7

Other features of novelty will be more fully described in connectionwith the accompanying drawing and will be more particularly pointed outand ascertained in and by the appended claims.

In the drawing :Figure l is a perspective view showing one form of thedevice of my invention with the upper and lower grips in an operativeposition. Fig. 2 is a view looking from the rear of Fig. 1. Fig. 3 is aplan view showing the upper gri s ad-v justed out of an operativeposition. ig. 4 is a side view showing the position'of the upper andlower grips when the upper grip is adjusted out of an operativeposition.

Like characters. of reference designate similar parts throughout thedifferent figures of the drawing.

As illustrated 1 designates a bench on which a lower or surface grip 2is preferably rigidly mounted to grip the work. The grip 2 is providedwith a base 3 which lies flat upon the bench 1 and which may be securedthereto by means such as screws 4:. The grip portion 2 is elevatedsomewhat with respect to the surface of the bench, as will be clearlyseen by reference to Figs. 1 and 4, and the work-engaging end of thesurface grip 2 is preferably serrated or toothed, as indicated at 5. Ialso bifurcate the lower or surface grip as indicated at 6 for insertionbetween the bifurcated portions of work of that character to" be heldedgewise. In order to stiffen the lower or surface grip I preferablyflange the same at 7 so as not only to extend the area of engagementwith-the work when the latter is dlsposed edgewise between the jaws ofthe bifurcated portions, but also to permit of forming the surface gripof sheet metal and imparting sufficient rigidity thereto by itsformation to withstand the stresses imposed thereon. The lower orsurface grip is extended beyond the edge of the bench 1 and is bent toform butts 8 into which a pin 9 is adapted to be extended.

I provide an upper grip which comprises a strip of metal composed of anupright portion 10 and a horizontal portion 11. The terminal .end of thehorizontal portion 11 is bifurcated, as indicated at 12, and I flangethe inner faces of the bifurcated portion as indicated at 13, to stiffenthe upper grip. The upper grip is hinged to the bench by means which maycomprise an an choring plate 14 provided with butts 15 through which ahinge pin 16 extends. The lower end of the upper portion 10 is bent toform a knuckle 17 whereby the upper grip will be hinged to the bench ina manner which will now be clear.

The upper grip, or the upright portion 10 thereof, is proportioned tolie between the butts 8, when in an operative position, and to 'beanchored in. an operative position by the pin 9. I

It will be seen from the foregoing construction that the upper grip canbe readily locked to the lower grip in an operative the lower and uppergrip will be in such vertical alinement that the work can be disposededgewise as shown in Figs. 1 and 3 for operation on the upper edgethereof. If on the contrary, the workman desires to operate upon one ofthe sides of the work, the locking means of pin 9 can be removed so thatthe upper grip can be detached and swung into an inoperative positionthereby leaving the area above the lower grip free for operation uponthe work in a flat position, as shown in Fig. 3.

It is believed that the advantages and utility of my invention will beclearly understood from the foregoing description and while I haveherein shown and described one position so that the bifurcated portionsof specific form of my invention, I do not wish to be limited theretoexcept for such limitations as the claims may import.

I claim 1. In a bench clamp, a bench, a lower work grip anchored to thebench for engaging the work at the surface of the bench, an upper griphinged to the bench for engaging the work at a point above the surfacegrip, and means for locking the upper grip to the lower grip anddisposing the upper grip in an operative position, substantially asdescribed.

2. In abench clamp, a bench, a lower grip I formed of sheet metal andanchored to the bench and provided with a toothed edge and,

a bifurcation extending from the toothed edge, a sheet metal upper griphinged to the bench and provided with a bifurcated portion adapted to bedisposed in vertical alinement with the bifurcated portion of the lowergrip, and means for locking the upper grip in an operative position andto the w lower grip, substantially as described.

8. In a bench clamp, a bench, a lower grip anchored to the bench andprovided with 7 means for engaging the work at the surface of the benchand having butts extending from the bench, an upper grip hinged to thebench andadapted to be'moved into an opform a work-grip jaw, thebifurcated portion being flanged to fit the same and provide arelatively wide area for grip of the work, an upper grip hinged to thebench and provided with a flange bifurcated portion adapted to bedisposed above the bifurcated portion of the lower grip, and means forlocking the upper grip in an operative position, substantially asdescribed;

In testimony whereof I afiix my signature in presence of two witnesses.
